If the MAC address of an interface is 00E0-FCEF-0FEC, the corresponding EUI-64 address is ( ).
If the MAC address of an interface is 00E0-FCEF-0FEC, the corresponding EUI-64 address is ( ).
To convert a MAC address to an EUI-64 address, the MAC address is split into two halves and 'FFFE' is inserted in the middle. Additionally, the Universal/Local (U/L) bit, which is the seventh bit of the first octet, needs to be toggled. For the MAC address 00E0-FCEF-0FEC, that first octet is 00. When the U/L bit is toggled, this becomes 02. Hence, the correct EUI-64 address is 02E0-FCEF-FFFE-0FEC.
According to several calculators its 2e0:fcff:feef:fec, thus A
Mac address is break in two blocks and in the middle you insert FFFE
Answer is C
Option A is correct
Based on the explanation from the forum below, A is the correct answer. https://community.cisco.com/t5/switching/mac-to-eui-64-conversion/td-p/1432287
B. Local. C. Radius. Explanation: B. Local: Refers to local authentication, where user credentials are stored locally on the router. C. Radius: Refers to authentication using a Remote Authentication Dial-In User Service (RADIUS) server. The router sends authentication requests to a RADIUS server, and the server validates the credentials. Option A (None) and Option D (802.1X$) are not accurate in the context of supported AAA authentication modes on Huawei AR G3 Series routers.
Correct one is C. Mac address is break in two blocks and in the middle you insert FFFE
Don't forget to change the 7th bit and assign FFFE in the middle.
